The Testament of Abraham.
There is no trace of the book of
Daniel in this work. One passage has been drawn into the Son of Man debate by
Flusser, who comments "According to the apocryphal Test. Abraham the son
of man is literally Adam's son Abel who was killed by the wicked Cain, for God
desired that every man be judged by a man (the identification is based upon a
verbal understanding that the son of man in Hebrew is ben-Adam).” This is
misleading. The term υιος ανθρωπου does not occur here at all. Abel is
described in ch xiii as υιος Αδαμ, but this is a literal description of his
universally recognized relationship to Ada, and if this passage is a direct
translation of a Hebrew original, it is clear that the translator was right to
understand בן (ה)אדם like this. This does not constitute identification of
anything with anything else. The statement πας ανθρωπος εξ ανθρωπου κριθησεται
explains why judgment is being carried out by a human rather than a
supernatural being, the contrast being with the divine statement εγω ου κρινω
ημας. It was never intended to explain why the man in question is Abel rather
than any other man. It is to be concluded that this passage provides no
evidence of a Jewish "Son of Man Concept". (Philip Maurice Casey, The interpretation of Daniel VII in
Jewish and patristic literature and in the New Testament: an approach to the
Son of Man problem [PhD Dissertation; Durham University, 1976], 422)
